3 * struct bus_type_private - structure to hold the private to the driver core portions of the bus_type structure.
4 *
5 * @subsys - the struct kset that defines this bus. This is the main kobject
6 * @drivers_kset - the list of drivers associated with this bus
7 * @devices_kset - the list of devices associated with this bus
8 * @klist_devices - the klist to iterate over the @devices_kset
9 * @klist_drivers - the klist to iterate over the @drivers_kset
10 * @bus_notifier - the bus notifier list for anything that cares about things
11 * on this bus.
12 * @bus - pointer back to the struct bus_type that this structure is associated
13 * with.
14 *
15 * This structure is the one that is the actual kobject allowing struct
16 * bus_type to be statically allocated safely. Nothing outside of the driver
17 * core should ever touch these fields.
